Answer:
Below
Step-by-step explanation:
● 2 ( x-1) - 5 (x+9)
● 2x - 1 - 5x - 45
● 2x -5x -1 - 45
● - 3x - 46
● 5x - 5 - 7x + 14
● 5x - 7x - 5 + 14
● -2x + 9
Simplify the following:
sqrt(5) - 16 + sqrt(15) - 8
Grouping like terms, sqrt(5) - 16 + sqrt(15) - 8 = sqrt(15) + sqrt(5) + (-16 - 8):
sqrt(15) + sqrt(5) + (-16 - 8)
-16 - 8 = -24:
Answer: sqrt(15) + sqrt(5) + -24
Answer:
D. For a ratio of 3:2, divide AB into 5 equal parts. Each equal part is 2 units, so the point that divides AB into a 3:2 ratio is 2.
Step-by-step explanation:
The complete question is:
<em>Point A is at –4 and point B is at 6. Which describes one way to find the point that divides AB into a 3:2 ratio? </em>
- In a 3:2 ratio there are 3 + 2 = 5 equal parts.
- The distance between points A and B is: 6 - (-4) = 6 + 4 = 10 units.
- Each equal part is 10/5 = 2 units.
- Point 2 is at 2 - (-4) = 6 units from -4
- Point 2 is at 6 - 2 = 4 units from 6
- Ratio 6:4 is equivalent to ratio 3:2
